Automobile comprising a crossbar, a technical front surface and a convergent element attached to each other

Abstract

An automobile that includes: a lower crossbar including longitudinal arms connected by links to vehicle side rails located above the arms; a technical front surface defining a plate, the plate including an inner face and an outer face and being adapted to be attached to a structural member of the vehicle; a shield convergent element including two absorption members capable of absorbing by deformation thereof the energy of a shock to the vehicle; each longitudinal arm of the crossbar being attached by a first fastener to the inner surface of the plate; and each absorption member being attached by a second fastener to the outer face of the plate so that the two absorption members are capable of deformation along a longitudinal axis of the vehicle upon a shock; the inner surface including ribs.

Description

OVERALL TECHNICAL FIELD[0001]The present invention relates to a motor vehicle comprising a lower crossmember comprising longitudinal arms connected, by connections, to side rail members of the vehicle which are situated above said arms, a front end module that forms a panel, the panel having an interior face and an exterior face and being intended to be attached to a structural element of the vehicle, a front spoiler convergent comprising two energy-absorbing elements able, by deforming, to absorb the energy of an impact on the vehicle, each longitudinal arm of the crossmember being fixed by a first fastener to the interior face of the panel, and each energy-absorbing element being fixed by a second fastener to the exterior face of the panel, so that the two energy-absorbing elements can deform along a longitudinal axis of the vehicle in the event of an impact.PRIOR ART[0002]FIG. 1 is a very schematic depiction of a front part of a motor vehicle, comprising a lower crossmember 1, ha...

AI Technical Summary

Benefits of technology

[0028]Because the crossmember is secured to the front end module and each energy-absorbing element is secured to the front end module also, the two energy-absorbing elements are able to deform along a longitudinal axis of the vehicle in the event of an impact, rather than along a vertical axis of the vehicle. The deformation of the spoiler is thus satisfactory, making it possible to comply with the relevant standards regarding low-speed impacts and intermediate speed impacts, and also making it possible to avoid destruction, particularly of the crossmember, in an impact.

[0029]The ribs are positioned on the interior face of the panel, to prevent rib / rib contact between the exterior panel and the energy-absorbing element, thus allowing better deformation of the energy-absorbing element in the impact.

Problems solved by technology

However, the known lower structure depicted in FIG. 1 is unable satisfactorily to comply with the relevant standards, particularly as a result of the deformation of the energy-absorbing elements along the Z axis, as shown by FIG. 2.

Such deformation along the Z-axis leads to damage to the components that make up the front end of the vehicle, particularly in the event of an intermediate speed impact.

However, such a configuration of the motor vehicle does not allow optimal deformation of the energy-absorbing elements along the longitudinal axis of the vehicle and may likewise lead to damage to the components in the event of an impact.
